Application filer? November 24,1911. Serial No. 662,168.

To all whom it may concern, c

Be it lrnown vthat I, CHARLES C. SNOB- enass, a citizen of the UnitedStat-es oi America, residing atl New Martinsville, in the county of`Wetzel and State of fest Virginia, have invented certain new and usefulimprovements in Trolleys, of which the Atollowing is a specilication,reference being had therein to the accompanying drawing'. Thisinvention. relates to trolleys and more particularly to lubricators forthe journal pin and wheel of the trolley harp;

The primary object of my invention is the provision ol' novel means, ina manner as will he hereinafter set forth, for using a pressurelubricator in connection. with the trolley harp, for thoroughlylubricating the journal pin and trolley wheel, whereby friction and"wea-r will be reduced to aminimum.

Another object of this invention is to provide positive and reliablemeans for locking a onurnal pin in a trolley harp, whereby said pincannot become accidentally displaced.

A further object oi' this invention is to` provide a trolley harp andlubricator that can oe used in connection with various types of trolleypoles.

A still further object ot this invention is to accomplish the aboveresults by 'a mechanical construction that is durable, inexpensive tomanufacture and highly etlicient for the purposes for which it isintended.

lWith the above and other objects in view the invention resides in thenovel construction, combination and arrangement of part-1. tohereinafter specilically described and then claimed.

' Reference will now be had to the drawing, wherein- Figure 1 is ay sideelevation of a trolley in accordance with this invention. Fig. 2 is abottom plan of the trolley harp. Fig. 3 is a horizontal sectional viewof the trolley harp on line of fr: of Fig. l, and Fig. t is an end viewo' one of the arms of the harp.

llhe reference numeral l denotes the upper end of a tubular trolley poleand secured in the upper end of said pole are rivets 2 or otherfastening means is a coupling piece 3 upon the end of which is mountedthe socket l of the trolley harp, said harp having oppositely disposedarms 5 and The socket l is retained upon the coupling piece 3 by acotter pin 7. The harp is secured on the coupling piece 3 a properdistance and the Cotter pin 7 is then placed in an opening to keep theharp from coming off. By putting the harp on in this manner, vibr; tionis eliminated, giving good contactO forv currentpassing down to motors.'The pin 7 extending through the coupling piece and having the split endthereof clenched, as at 8.

rllhe under side of the harp, adjacent to the arms 5 and 6, is providedwith an enlargement 9 and the-arm 5 has an angularly disposed rib 10terminating at a boss 1.1 carried by the outer side of tie arm 5. rlheenlargement 9 and the rib 10 are provided 70, with a port 12 extendingfrom the rear end of the enlargement 9 to the boss 11, said port beingin communication with a recess 13 formed in the boss with said recess incommunication with an opening 14 having the, 7.5 walls thereof screwthreaded.

Screwed into the opcning'll is the threaded end of a journal pin 15,said `pin having the opposite end thereof in an opening 16 providedtherefor in the arm 6. The outer 3.0 end of the pin 15 is reduced toform a shank 17, whereby" a wrench or other instrumentA can be employedfor screwing the journal pin into the arm 5. The outer end of thejournal pin has a transverse opening 18 in 85 communication with alongitudinal groove 19 formed in the outer side of the arm 6, at the endthereof. Mounted in the opening 18 is a cotter pin 21 that has the endsthereof Within the groove 19 to prevent the journal 90 pin 15 fromrotating after having been mounted in the arms of the harp. Thejournalpin 15 has a longitudinal port 21 having one end thereof iiared, as as22 and in cornmunication with the recess 18. The opposite end of theport terminates at a point intermediate the ends of the journal pin andis in communication with a duct 22.

Revolubly mounted upon the vjournal pin 15 is a trolley wheel 2-l or theordinary and 100 well known type and the bore of this wheel is adaptedto be lubricated'by a lubricant passing through thel duct 12, recess 13and ducts 21 and 22.

The rear end of the enlargement 9 has 105 a socket 25 with the Wallsthereof screw threaded, and said enlargement is provided with adepending eye 26 towhich a cord or rope can be attached to lower thetrolley or remove the wheel 2e trom a trolley wire M0 or electricconductor 27. Mounted in the socket 25 of the enlargement 9 is acoupling pipe 28 to which is connected a pressure 1ubricator 29.

The pressure lubrieator is of the ordinary and Well known type embodyinga reservoir containing a piston that .can be adjusted to force lubricantinto the ducts l2, 21 and 22. rIhe lubricator 29 is braced by an arm 30carried by the under side of the harp socket .4.

It is thought that the operation and utility of the lubricator will beapparent without further description, and while `in the drawing there isillustrated a preferred embodiment ot' the invention, it is to beunderstood 4that the structural elements are susceptible to suchvariations as fall Within the scope ofthe appended claims.

TWhat I claim is l. In a trolley, a harpbody, oppositelydisposed armscarried thereby,pan enlargement carried by the under side of said harpbody, said enlargement and one of said arms having a duct formedther-ein, a vjournal pin mounted in said arms and having ducts formedtherein in communication with the duct of said enlargement and said arm,a trolley wheel revolubly mounted upon said pin, and a pressurelubrieator carried byv said enlargement and in communication with theduct thereof., v

2. In a trolley, a harp body, oppositely disposed arms carried thereby,an enlargement carried by the under side of said harp body, saidenlargement and one of said arms having a duct formed therein, a journalpin mounted. in said arms and having ducts formed therein incommunication with the duct of said enlargement and said arm, a trolleyivhe'el revolubly mounted upon said pin, a pressure lubricator'carriedby said enlargement and in communication With the duct thereof, and anarm r:arried by the under side of said harp body for bracing saidpressure lubricator.

cation ivith the duet of said enlargement,

a trolley Wheel revolubly mounted upon said pin, a eotter pin extendingthrough the end of said journal pin and engaging in the outer Wall ofone of saidarms to prevent 'said journal pin from rotating, andapressure lubricator carried by said enlargement and in communicationwith the duct thereof. 4. In aV trolley, a harp;body, oppositelydisposed arms carried thereby, an enlarge- .ment carried by the underside of said harp body, said enlargement having aduet formed thereinextending into one ofsaid arms, a journal pin extending through one ofsaid arms and having the end thereof mounted in the arm provided withthe extended duet of said enlargement, said pin having ducts formedtherein in colmnunieation with the duct of said enlargement, a trolleywheel revolubly mounted upon said pin, a cotter pin extending throughthe end of said journal pin and engaging in the outer wall of one ofsaid arms to prevent said journal pin from rotating, a pressurelubricator carried by said enlargement and in communication with the.duct thereof, an arm'earried by the under side of said harp 'body forbracmg sald lubricator, and an eye oarried by the under side of saidenlargement.

In testimony whereof I aiiix my signature in the presence of twoWitnesses.
